Hi Scott,
I have 2 applications using a number of Value Objects. One of these is a Web Service. In the Web Service implementation the Timestamp is in one of the Value Objects however its value is nver set, and always null. On my development server this seems to work fine and seems to deal with it (maybe false comfort).
This is the same scenario on the deployment Server, however here it seems to fail. It's as if its denomination xsi:null="true", is sufficent to allow it through the soap system, i.e. since it is always null, soap has never attempted to try and deserialize it.
Hope this makes sense.

I don't see how it could ever work, unless some version of
java.sql.Timestamp has a default ctor. The following code in
BeanSerializer creates the bean:
private Object instantiateBean(Class javaType)
throws IllegalArgumentException
{
try
{
return javaType.newInstance();
}
catch (Throwable t)
{
throw new IllegalArgumentException("Unable to instantiate '" +
StringUtils.getClassName(javaType) +
"': " + t.getMessage());
}
}
The newInstance is only going to work if the class has a default ctor
(or in Sun's terminology, a "nullary constructor").
